I guess it's highly individual.
My pj is softening the picture quite a bit, so in order to get a sharp "focused" image, I have to make it "oversharpened" on my monitor.
I use recizex2 tab2 luma=1.05 and asharpen 1.8/3.85
That is way to much on a std. display, but at my wieving distance, and setup, it just looks nice, crisp, and highly "focused".
Go for what ever looks the best on your system, and ignore what is concieved as the only way to do it.
